Width in millimetres, and it must match the binding
Ski crampons, compared
A ski crampon is a steel comb that clips beside the boot on a touring binding and bites when the snow is too hard for a skin. It is the narrowest compatibility question in the whole catalogue, and it is decided by one number: the width in millimetres. The corpus shows 90, 100, 105 and 110 mm, and the crampon must be at least as wide as the ski at the waist — too narrow and it will not straddle the ski, too wide and it stops biting. The second condition is harder, because it is a system rather than a size: the crampon mounts to a specific binding. A crampon made for one maker's pin binding will not enter another's slot, and the listings that name the binding — Kingpin, TLT — are the ones telling the truth about it. Anything sold as universal is asking the buyer to check. The tooth depth decides what the crampon can do: shallow teeth handle a frozen skin track, deeper ones hold on refrozen spring crust, and depth costs weight. The material is steel or aluminium, and the trade is exactly what it sounds like. The weight per pair closes the argument, because a crampon lives in a pack until the one morning it is needed. Note also what this shelf is not: boot crampons for walking on ice are a different product, they appear in this corpus, and they have their own family here. We compare fits, width, tooth depth, material, packed and weight per pair.
